สรุป	Intrinsic case study is a qualitative research method developed by Robert E. Stake in which a single, bounded case is studied in depth for its own inherent interest — not to illustrate a theory or to generalize, but because the case itself is unusual, revealing, or otherwise worthy of close attention. The researcher seeks a thick, holistic understanding of the particular: its context, its actors, its processes, and what makes it distinctively what it is.	Action research is a collaborative research methodology in which researchers work with practitioners and community members to investigate a problem, implement change, and evaluate outcomes, cycling through reflection, action, and learning. Developed by Kurt Lewin (1946), action research bridges research and practice, aiming simultaneously to produce knowledge and practical improvement.	Case study research is a qualitative research design that investigates a specific phenomenon, individual, group, organisation, or event in depth within its real-world context. Systematised by Robert K. Yin in 1984, it supports single-case and multiple-case designs and draws on multiple data sources — interviews, observation, documents, and artefacts — to build a rich, contextualised account of a bounded unit.
